Pair of Vintage Pull Toy Ducks

Description

Two vintage, possibly antique, pull toys, one tin or aluminum and one likely cast iron or steel. They propel forward on wheels, but intended winding and path of pull string is unclear and likely can be restored to optimal original configuration. The larger duck is about 7 inches long and the smaller one about 4 inches.
Both have signs of wear with fading and scrapes.
